RA, my bottom cam is closer to the limb than the top cam. If the cams are way out of whack, you should be able to feel the cable "jump" into the groove on the cam. Could you feel anything on yours? Mine shoots fine, with no felt bumps or jumps. I measured the cams and will keep an eye on them.
Phil.
